GEORGE H. HARDMAN, OF FALL RIVER, MASSACHUSE'FTS, ASSIGNOR OF ONE-HALFTO FRANK S. BRUNDAGE, OF FALL RIVER, [MASSACHUSETTS MACHINE FORMANUFACTURING SANITARY NAPKINS.

neoaiss.

To all whom it may concern Be it known that 1, GEORGE H. HARDMAN, of thecity of Fall River, in the county of Bristol and State of'Massachusetts, have invented a certain new and useful Machine formanufacturing sanitary napkins and has for.

its object to produce a machine of this character which automaticallyinserts a prede termined amount of cotton, or other suitable absorbentmaterial, into a fabric casing, then folds or flattens said casing andthen severs the casing into predetermined lengths.

To this end the invention consists'in the novel features of constructionand arrangement of parts hereinafter shown and described and moreparticularly set forth in the claims; 4

In describing the invention in detail reference will be made to theaccompanying drawings, in which Figure 1 is a side view of my novel ma-Fig. 2 is a plan view of the same. Fig. 3 is.a longitudinal section online 'mm, Fig. 2. F ig. 4 is a transverse section on line g y, Fig. 2.Fig. 5 is transverse section on line z2, Fig. 2. Fig. 6 is an. end View.Fig. 7 is a detail.

Referring to the drawings, 1 represents the bed of the machine which'issupported upon suitable legs or standards 2. Mounted upon .the bed 1 atone end are two pair of uprights 3 and'4, which are spaced any desireddistance apart depending upon the length of filling desired for thenapkin.

Journaled in the uprights 3 are two shafts 5 and 5%, upon each of whichis secured a frictionffeed roll 6 and 6' respectively and 'journaled inthe uprights 4 are two shafts 7 and 7','upon each of which is secured afriction feed roll 8 and 8, respectively. Extending between the uprights3 and 4 in line with the top surfaces of the bottom rolls 6 and 8 is atable or support 9.

Mounted upon the bed 1 adjacent the upright 4 is an upright block 10which extends across said bed transversely and-is provided with acentral rectangular opening 11 extending through the same, as shown inFigs.

'3 and 5. Secured upon one side of the block 10-and upon opposite sidesof the opening 11 are two elongated arms 12 arranged parallel to eachother and to the bed 1. Formed upon the outer side of each of the arms12 is a horizontal rib l3 and a series of ver-, tical ribs 14, as shownin Figs. 2 and 5. Removably held by friction upon the arms 12 is a tube15.

J ournaled in the block 10 and extending through the opening 11 is themain driving shaft 16, which carries a pulley 17 mounted to rotate inthe opening 11 and having its upper'surface in line with the uppersurface:

of the feed rolls 6 and 8, as shown in F ig. 3. J ournaled in the freeends of the arms 12 is shaft 18 which carries a loose pulley 19, whichcooperates with the pulley 17 to drive a conveyer belt or apron 20. I

Secured upon the end of the bed-1 ad jacent the free ends of the arms 12is a bracket 21, to which is pivoted an upright adjustable frame 22 inwhich is journaled a shaft 23 which carries a feed roll 24, the uppersurface of which -is arranged in line with the upper portion of theconveyer belt 20. Also journaled in the frame 22 directly above theshaft 23 is a shaft 25 which carries a circular brush '26 arranged tocooperate with said feed roll 24. The frame 22 is held in adjustedposition by a thumbnut 27 andbolt 28 secured in the bracket 21. Securedupon brackets 29 extending from the frame 22 is a fixed knife member 30and pivoted upon said fixed knife member 30 is a movable knife member 31having a tail portion 32, as shown in Fig. 6. Secured to the brackets inline with the upper surface of feed roll 8 is a tableor support 33, thefree end of which is arranged in line with and in close proximity to theupper surface of pulley 17.

The mechanism for driving the various parts of the machine will now bedescribed.

Secured upon one end of the main driving shaft 16 is a fixed drivingpulley 34 and a loose pulley 35.

meshes with a bevel gear 37 secured upon a shaft 38' which is journaledin brackets 39 intermittent bevel gear 40 arranged to co- Upon theopposite end of 'the main shaft 16 is a bevel gear 36 which operate withan intermittent bevel gear 41 securedupon the end of shaft 51. Alsosecured upon shaft 5 is a gear 42 which meshes with a gear 43 upon shaft5. Secured upon shaft 38 is a bevel gear 44 which meshes with a bevelgear 45 upon shaft 7 and secured upon shaft 7 is a gear 46 which mesheswith a gear 47 on shaft 7. shaft 38 adjacent the opposite end is a bevelSecured upon the gear 48 which meshes with a bevel gear 49 uponshaft 23.Also. secured upon the shaft 38 adjacent the bevel gear 48 is a cam 50,which'is arranged to coiiperate with the tail portion 32 of the movableknife member 31 to open and close the same. Said tail portion 32 .isheld against the face of cam 50 by a spring 32. l I

The operation of the machine will be readily understood. A supplyof'cotton or other absorbent material A is fed from a can or otherreceptacle between the feed rolls 5 and '5 which rotate intermittently.A supply of tubular fabric B is placed upon the tube 15 and said tube isplaced upon the arms 12. The machine is nowv ready to be started. As thefeed rolls 5 and 5 revolve,

the cotton is fed alongon the table 9 and between the continuouslyrotating feed rolls 7 and 7'. WVhen now the intermittentfeed rolls 5 and5 cease to operate, the .feed rolls 7 and 7 which continueto rotate,will sever the cotton A at the point where it is gripped by the feedrolls 5 and 5 and continue to feed said severed portion 0, whichconstitutes the amount required for a filling for one napkin.Saidfilling G is then fed by the feed rolls 7 and 7 along the table 33and onto the con veyer belt 20, which continues to feed it along theinterior of the-tube 15. J ust before said filling C reaches the outeror free end of said tube 15, the end of the tubular fabric B is fedbetween the feed roll 24 and brush 26. The fillingC- is'then fed by thevconveyer belt 20 into said tubular fabric and between the feed roll 24and brush 26, thence between the fixed knife 30 and movable knife 31which is operated-by the cam 50, to sever the tubular fabric and afinished napkin 'D. is deposited from the machine.

It willbe seen that after the tubular fabric has'once been insertedbetween the feed roll 24 and brush 26, the action of the ma:

chine is entirely automatic and said ma chine will continue to depositcompleted napkins until the supply of stock is exhausted. When thesupplyof tubular fabric ll is exhausted, the empty tube 15 is removed from thearms 12 anda loaded tube is slipped upon said arms where it is held tionof ribs 13 and 14.

It will be understood that various changes in the form, proportions,size and minor details of the machine may be made without departing fromthe spirit and scope of the invention and that the length of the fillingA.

by the fricand completed napkin can be varied by simply changing. thesize of the bevel gears upon shaft 38 sons to increase or decrease thespeed of the feed rolls, as desired.
